PROJECT DESCRIPTION
When assessing whether to invest in an asset or not, an investor wants to look not only at how much money they could make but also at how much risk they are taking. The Sharpe Ratio, developed by Nobel Prize winner William Sharpe some 50 years ago, does precisely this: it compares the return of an investment to that of an alternative and relates the relative return to the risk of the investment, measured by the standard deviation of returns. In this project, the Sharpe ratio will be applied to real financial data using pandas
